Knick Portavo 907 Multi pH Multiparameter Portable Meter

Resource type: 
Data sheet
Date of creation: 
14 December 2015
Library code: 

Multiparameter portable meter with additional analog pH measurement capability. For all digital Memosens pH, conductivity and oxygen sensors and for analog pH electrodes.

The only portable device for all Memosens parameters. Also for conventional analog sensors. The powerful Li-ion battery can be charged in the device via USB. The clear network diagram provides an at-a-glance view of the sensor condition.

Comprehensive data logger

The following logging types can be selected:

  • Manual logging
  • Time-controlled logging at a fixed interval
  • Signal-controlled logging of measured value and temperature
  • Combined time- and signal-controlled logging
  • Threshold-controlled logging with pre-trigger

The data logger for up to 10,000 entries records point of measurement, annotation, sensor ID, sensor serial number (Memosens), primary value, temperature, time stamp and device status.

User-friendly software

Portavo 907 proves that a high level of functionality and easy use are not mutually exclusive. It proceeds step by step through the calibration procedure. Technical terms are clearly explained in the context-sensitive help.
